Materials That Matter

We made this page for the parent who already flips the tag, already checks the certifications, and already knows "organic cotton" doesn't mean what most brands imply it means.

Here's the full picture on every material, every certification, and every supplier behind Hahaha. Nothing hidden. Everything verifiable.

"Organic cotton only describes how the cotton was grown, not what happened after harvest. Once the cotton is picked, it can be bleached with chlorine, dyed with heavy metals, and treated with wrinkle-resistant finishes that contain formaldehyde. The same chemical used for embalming. And none of that has to be disclosed."

We don't grade our own homework. Sustainable Jungle evaluated us across 22 criteria covering materials, labor, supply chain, and transparency, and listed us in their 2026 ethical kids' clothing directory.

SMALL BATCH

The Skin of Our Children is 30% Thinner Than Ours

Research shows that a baby's skin is about 30% thinner than an adult's, meaning it's more permeable and absorbent. When chemicals sit on clothing, they don't just stay there. They make their way into the bloodstream. And kids don't have fully developed detox systems yet. Their liver and kidneys are still maturing. So even small exposures can build up faster and linger longer. This is why we obsess over every step of production. Because what touches their skin matters more than people think.

We Test for 350+ Harmful Substances

Independently verified by Testex, we guarantee quality you can trust.

🔬 OEKO-TEX Standard 100

This independent lab tests our finished fabrics for over 350 harmful substances, including:

Pesticides
Heavy metals like lead, cadmium, mercury
Formaldehyde
Phthalates (hormone disruptors)
Allergenic dyes
PFAs (known as forever chemicals)

Why double certification?

Because kids put clothes in their mouths.
They sleep in them for hours.
They sweat in them on playgrounds.
Because we wanted zero doubt!

VELCRO®️

When kids swap patches 20 times a day, the closure has to outlast the obsession.

We use genuine VELCRO® Brand hook and loop fasteners, sourced directly from their authorized supplier, on every customizable garment and every patch.

Why it matters:

Engineered for thousands of open-and-close cycles without losing grip
No sharp edges or metal parts against children's skin
Consistent performance wash after wash
The same closure trusted by NASA, the military, and medical device makers

Cheap hook and loop fails within months. VELCRO® Brand fasteners are the reason one hoodie can tell a hundred stories.

YKK Zippers

The tiny moment that decides whether your kid wears the jacket or fights you about it.

Every Hahaha zip-up jacket uses a genuine YKK zipper, the same brand found on Patagonia, The North Face, and Levi's.

Why it matters:

Precision-engineered teeth for smooth, snag-free operation (so small hands can zip themselves up)
Corrosion-resistant and colorfast through hundreds of washes
No sharp burrs or rough edges against children's skin
The reason they can get out the door faster in the morning

Cheap zippers fail at the worst moment: mid-tantrum, in the rain, on the way to school. YKK is the zipper that just works.

🧢 How to Keep Them Soft, Safe, and Lasting

We recommend washing new clothes before the first wear to remove any manufacturing residues.

For Hahaha garments:

Wash cold
Use fragrance-free detergent
Skip fabric softener
Tumble dry low or air dry
Remove patches before washing to keep hook-and-loop fresh

Our organic cotton actually gets softer with every wash.
